Electroacupuncture on ST36 and GB39 Acupoints Inhibits Synovial Angiogenesis via Downregulating HIF-1α/VEGF Expression in a Rat Model of Adjuvant Arthritis

Figure 4

Measurement of synovial CD34 expression by immunohistochemistry. H&E-stained sections from the control group, demonstrating CD34 was only expressed in a small amount in the ankle joint, the AA group and the AA+sham EA group illustrating a very large number of CD34 expression in the swollen joints, and the AA+EA group, demonstrating less number of CD34 expression in the ankle joint. Mean inflammation score (+SD) on a 3-point scale. Compared with control group, P < 0.05 and P < 0.01; compared with AA group, ^#P < 0.05 and ^##P <0.01, n=10 (n=10) (×200).
